SPECIFICATION forming I Application filed August 26, 1902.

To all whom it may concern.-

Be it known that we, ALLEN D. LINN and ITHIEL J. C1LLnY,'citizens of the United States, residing at Grand Rapids,in the county of Kent 5 and State of Michigan, have invented certain new and useful Improvements in Sprinklerthe fusible plates have been separated by excessive heat, \VVe attain the objects named. by the mechanism illustrated in the accompanying drawings, in which- 1 Figure 1 is an elevation of an automatic-fireextinguisher system cut away at X and a secthe head, hereinafter described, in position. Fig. 2 is a plan of the same. Fig. 3 is an end elevation of the-sprinkler-head anddonnectionssbowing the form and application of the fusible plates or link; and Fig. 4 is an edge elevation of. the plates .or link formed by the plates.

Similar letters refer to similar parts throughout the several views. I

i A represents the mainline of water-pipe in an automatic fire-extinguisher system.

B is the cross that connects the sprinkler head in the system, and C represents a form of shut-ofi' recently constructed by us and which is fully illustrated-and described in our recent application for United States Letters Patent covering the same, the valve 0 being designed to be raised to position to. shut 0d the flow of water through the sprinkler-head is necessary or desirable to do so.'

D is a sectional elevation of the sprinkler-. head, showing the seating of the. valve E.

The valve E is provided'with a downwardiy: J

- surface is countersunk'f or the reception of the projecting point f of ther-armF'bf .the.-.leve"r F, so that the valve will be held steadily inr? position when opened for the flow-ofwater by the action of the arm aboveand ofzthestem i through the bridgebelo-w. a I v To avert the danger of ,outflowing coming in contact with the fiusible-plates orv link G before the same hasdisconnected and preventing it from unsol'dering we make use of a horizontal arm H and ,-lever F, thus carrying the link some distance to one side of. instead of directly over the-valve, as in :the sprinkler-heads in common use,,and make the standard D, which supports thelever F,- broad enough so that there is littleor no danger of a moderate flow of water passing by it and striking the link G G.

The stationary arm H, the standards H and D, and the base D are cast in one piece,- thes'tandard D being provided with a mortise for the reception of the lever F F, which is pivoted therein, as shown in Fig. 1, and the standard H is provided with an opening it, through which a tool may be passed to\form or repair thevalve-seat in thebase D.

The link G is composed of two thin plates of metal, the outer sheet G being open at the lower end and designed topass over-the arm H and to-solder to the plate G with a solder I that melts at a very low degree of heat. The

lower or inner plate G is formed-with a bow or bearing g at the upper end that-is situated just below the arm H and some little distance above the uppersurfa'ce of the arm F, so that when the plates have been disconnected by melting the solde r. in the usual manner the plate or linkv G will drop a little distance before striking the arm F. To render thisconstruc-v tion av'ailable'for thepurpose for which it is designed, we suspenda weight Lfrom the lug g,

so that the contact of the link G with the arm F will be by a. sudden quickstroke, which will :forcethe armdown with more than ordi- .naryiforce and willforce the arm F" under thelflange'E of the valve and positively insure the unseating of the valve. The flange E is alsc'utilized to form the vertically-escap ing column or water into a horiz'ontaily-radi sting spray.- r

J represents a link designed to be used for securing the lever F in place and seating the valve so that water cannot flow through after the link G has been disconnected and it is deand inconvenient sired to close the valve and stop the flow of water. This is done by throwing the lever up to place and then carrying the auxiliary link J over the arm H,-as indicated by its dotted lines. This device is designedprincipally for use where the head is being applied to an old system of piping, where it would be expensive to apply the shut-otf shown atCcin Fig.1.

Having thus fully described our invention, what we claim as'new, and desire to secure by Letters Patent of the United States, is-

1. In combination with the valve'and valveseat of a sprinklenhead for automatic fireextinguishers, a supporting-frame constructedabove the valve, an arm projecting horizon tallyfroni the top of the frame, a lever pivoted to the frame below the arm, one arm of said lever projecting to the center of the frame and engaging a countersink in the top of the valve, a second arm extending under and in position to engage the rim of the valve, and the main arm of the lever extending out under and parallel with the arm on the frame, and a fusible link supporting it, substantially as and for the purpose set forth.

2. In combination with the valve and valve- 7 seat of a sprinkler-head, a horizontalsupporting-arm,-a lever pivoted below the arm and one arm 'of said lever acting upon the upper surface of the valve, a flange upon the valve, a fusible link securing the outer end of the lever to the supporting-arm, the inner plate of said link forming a bow at the upper end and having a depending lug at the lower end, a weight'suspended from said lug, and an arm projecting from the lower surface of the lever to and under the flange on the valve,substantially as and,for the purpose set forth.

3; In combination with a sprinkler-head having horizontal supporting-arm and lever, a fusiblelink formed of two plates, the upper of said plates forming a bow at the upper end and open at the lower end, the lower orinner plate forming a bow at the upper end below the bow of the upper plate and connected at the lower end, said lower plate soldered to the upper-plate, and a weight connected with the lower end of said lower plate, substantially as and forthe purpose set forth.
